Transponder Chips

If your car is made within the last 20 years, chances are it contains a transponder chip within of it. It's the tiny piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your car.

When activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then absorbed by a special antenna that is attached to the barrel of ignition. The computer system of the vehicle can then verify that the chip in the key's transponder is the correct one for your car.

A circuit within the induction coil will emit signals when the transponder is inserted into the ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer onboard the car key reprogrammed is able to recognize the signal as being correct it will turn off the vehicle immobilizer, allowing the engine to start.

If the car does not recognize the transponder signal as the proper one, it will stop the engine from starting and will alert you by flashing its lights and sounding an alarm. This feature is intended to discourage people from trying to alter the vehicle, but it's not a 100% security measure. A skilled and determined thief could still bypass this system with a specially designed device that blocks the signal.

When you press the button on a key fob, the microchip transmits a signal to the receiver in the car with which it is linked. The receiver compared the information with the permitted signals stored in the key fob, and then it opens or closes the car door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to operate.

Once the car is linked with a specific fob, it will only accept signals from the device that is associated with it. Other fobs won't work with the car key reprogram, despite the fact that they appear similar. This safeguards the integrity of the computer system of the car and blocks unauthorized key fobs gaining control of it.

Most dealerships with newer cars will only deal with cars that have original fobs, or genuine replacements offered by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security knowledge which can only be obtained in the dealer's service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems -- can be programmed by consumers without the need of dealers.
